2022-05-13hw/pxb: Allow creation of a CXL PXB (host bridge)Ben Widawsky
This works like adding a typical pxb device, except the name is 'pxb-cxl' instead of 'pxb-pcie'. An example command line would be as follows: -device pxb-cxl,id=cxl.0,bus="pcie.0",bus_nr=1 A CXL PXB is backward compatible with PCIe. What this means in practice is that an operating system that is unaware of CXL should still be able to enumerate this topology as if it were PCIe. One can create multiple CXL PXB host bridges, but a host bridge can only be connected to the main root bus. Host bridges cannot appear elsewhere in the topology. Note that as of this patch, the ACPI tables needed for the host bridge (specifically, an ACPI object in _SB named ACPI0016 and the CEDT) aren't created. So while this patch internally creates it, it cannot be properly used by an operating system or other system software. Also necessary is to add an exception to scripts/device-crash-test similar to that for exiting pxb as both must created on a PCIexpress host bus.

2022-05-13hw/pci/cxl: Add a CXL component type (interface)Ben Widawsky
A CXL component is a hardware entity that implements CXL component registers from the CXL 2.0 spec (8.2.3). Currently these represent 3 general types. 1. Host Bridge 2. Ports (root, upstream, downstream) 3. Devices (memory, other) A CXL component can be conceptually thought of as a PCIe device with extra functionality when enumerated and enabled. For this reason, CXL does here, and will continue to add on to existing PCI code paths. Host bridges will typically need to be handled specially and so they can implement this newly introduced interface or not. All other components should implement this interface. Implementing this interface allows the core PCI code to treat these devices as special where appropriate.

2021-03-22pci: introduce acpi-index property for PCI deviceIgor Mammedov
In x86/ACPI world, linux distros are using predictable network interface naming since systemd v197. Which on QEMU based VMs results into path based naming scheme, that names network interfaces based on PCI topology. With itm on has to plug NIC in exactly the same bus/slot, which was used when disk image was first provisioned/configured or one risks to loose network configuration due to NIC being renamed to actually used topology. That also restricts freedom to reshape PCI configuration of VM without need to reconfigure used guest image. systemd also offers "onboard" naming scheme which is preferred over PCI slot/topology one, provided that firmware implements: " PCI Firmware Specification 3.1 4.6.7. DSM for Naming a PCI or PCI Express Device Under Operating Systems " that allows to assign user defined index to PCI device, which systemd will use to name NIC. For example, using -device e1000,acpi-index=100 guest will rename NIC to 'eno100', where 'eno' is default prefix for "onboard" naming scheme. This doesn't require any advance configuration on guest side to com in effect at 'onboard' scheme takes priority over path based naming. Hope is that 'acpi-index' it will be easier to consume by management layer, compared to forcing specific PCI topology and/or having several disk image templates for different topologies and will help to simplify process of spawning VM from the same template without need to reconfigure guest NIC. This patch adds, 'acpi-index'* property and wires up a 32bit register on top of pci hotplug register block to pass index value to AML code at runtime. Following patch will add corresponding _DSM code and wire it up to PCI devices described in ACPI. *) name comes from linux kernel terminology Signed-off-by: Igor Mammedov <imammedo@redhat.com> Message-Id: <20210315180102.3008391-3-imammedo@redhat.com> Reviewed-by: Michael S.

Note that even though romsize is a uint32_t, it has to be between 1 (because empty ROM files are not accepted, and romsize must be greater than the file) and 2^31 (because values above are not powers of two and are rejected).

2019-10-29pci: add option for net failoverJens Freimann
This patch adds a failover_pair_id property to PCIDev which is used to link the primary device in a failover pair (the PCI dev) to a standby (a virtio-net-pci) device. It only supports ethernet devices. Also currently it only supports PCIe devices. The requirement for PCIe is because it doesn't support other hotplug controllers at the moment. The failover functionality can be added to other hotplug controllers like ACPI, SHCP,... later on.
